Envoy is an open source edge and service proxy designed for cloud-native applications. From 1.23.0 until 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability has been identified in Envoy's zstd decompressor implementation ZstdDecompressorImpl. When zstd decompression is enabled, processing a...

GHSA-XV9W-7V6Q-HPJH fluent-plugin-s3 Vulnerable to Denial of Service (DoS) via Decompression Bomb in `in_s3`

The fluent-plugin-s3 plugin specifically the ins3 input plugin supports reading and decompressing heavily compressed files such as gzip, lzma2, and lzop from Amazon S3. It was discovered that the plugin read the entire decompressed payload into memory at once without enforcing a strict size limit...

GHSA-J9CW-HWQF-85W7 Fluentd is Vulnerable to Denial of Service (DoS) via Gzip Decompression Bomb in `in_http` and `in_forward`

Fluentd's inhttp and inforward plugins support receiving gzip-compressed data. While Fluentd correctly enforces size limits on the incoming compressed payloads e.g., via bodysizelimit or chunksizelimit, it was discovered that there is no limit enforced on the size of the decompressed data. If a...

PT-2026-60346

Name of the Vulnerable Software and Affected Versions 7-Zip versions prior to 26.02 Description A heap-based buffer overflow exists in the XZ decoder component when processing specially crafted XZ chunked data. The issue occurs within the MixCoder Code function in the XzDec.c file, where the...

PT-2026-53004

Name of the Vulnerable Software and Affected Versions Fluentd versions prior to 1.19.3 Description The in http and in forward plugins support gzip-compressed data but only enforce size limits on the compressed payloads via settings like body size limit and chunk size limit. Because no limit is...

CVE-2026-54250 K3s: ZIP Archive Path Traversal Vulnerability in etcd Snapshot Decompression

K3s is a fully conformant production-ready Kubernetes distribution. Prior to 1.35.3+k3s1, 1.34.6+k3s1, v1.33.10+k3s1, a path traversal vulnerability exists in K3s's etcd snapshot decompression functionality. Zip files containing archive members with maliciously crafted names can be written to...

CVE-2026-54250

CVE-2026-54250 affects K3s by a ZIP archive path traversal in the etcd snapshot decompression. Before versions 1.35.3+k3s1, 1.34.6+k3s1, and v1.33.10+k3s1, a crafted ZIP member can be written to arbitrary filesystem locations when restoring an etcd snapshot, due to the decompression process. Impa...

CVE-2026-54278

A flaw was found in aiohttp, an asynchronous HTTP client/server framework. An attacker could send a specially crafted compressed request body that, during cleanup, would be decompressed into memory in one large chunk. This could potentially lead to a Denial of Service DoS condition, where the...
